SPECIFICATION forming part of Letters Patent No. 281941, dated July 24,18.83.

Appncation flied Maren-2,1383. (Manen 1'0 all wiz/0m, it may concern: i

Be it known that I, ALBERT L. STOUT, a citizen of the United States,residing at Middletown, in the county of Wilson and State of Kansas,have invented a new and useful Flood- Gate, of which the following is aspecification.

My invention is designed to obviate the necessity of giving personalattention to ood or ywater gates in time of freshets or rises inwater-courses. It is automatic inprinciple, and will (being properlyadjusted) open when the pressure of the rising water makes it necessaryfor the free passage thereof, and will close when the pressure of thewater ceases, and at the same time will answer the purpose of a fence.

In the accompanying drawings, forming a part of this specification, andon which like letters of reference indicate corresponding parts, Figurel represents a perspectiveview of my improved flood-gate, showing thegates partially open, as viewed from the upper sideor toward the head ofthe stream; and Fig. 2 represents a similar view of my gate as viewedfrom the lower side or toward the mouth of the stream. Y

The letter A indicates the upper gate; B, the lower gate; C, theoperating-rod; I), the lefthand post; E, the right-hand post, F, therighthand post on which the gate A swings, and G the left-hand post onwhich the gate B swings.

The letter H indicates the short operatingrods extending from the bottomof the posts F and G.

I indicates the longitudinal beam forming vthe rear portion of the gate-Aand J J the upright posts of the said gate. The letter K refers to thegage or pressure-board, which is adjustably secured to the gate A bymeans of the staples 5, which fit over the uprights .I and the pin 4,which extends through the horizontal beam I, the adjustment of the boardbeing effected by withdrawing the pin 4 and elevating or lowering thegate until one of the upper or lower apertures formed therein rcgisterswith the said pin. Upright rods 1 serve to connect the upper and lowerhorizontal beams of the gate B, the post G of which is provided withstuds or trunnions 3, which play in the hinges 2.

The gage or pressure-board, indicated by the letter K, is adjusted inthe manner above described, so as to be raised or lowered according tothe depth of water, presenting a broad smooth surface, against which thepressure of the water acts, whereby the gate is opened and a freepassage for the water thus provided. When the water subsides, thepressure thereof against-the lower gate, B, closes it, and it in turncloses the upper gate through themedium of the rods C and H.

Having thus fully described my invention, what I'claim as new, anddesire to secure by Letters Patent, isp l. The combination, in anautomatic iioodgate, of the two gates hinged, respectively, to postslocated approximately opposite each other, one of said gates beingprovided with an adjustable pressure-board, with the operatingrodsecured at its respective ends to said gates, substantially as shown anddescribed.

2. The combination, in an automatic floodgate, of the two gates hingedto separate posts, one of which is provided with an adjustablepressure-board and fastening devices for said boarol7 with anoperating-rod secured to the hinged end of each of the gates,substantially as shown and described.
